MACHINERY FOR DRESSING SEWING-THREAD, WARPS, 0R YARNS.

Specification of Letters Patent No. 17,384, dated May 19, 1857.

T0 all 10h-0m t may concern Be it known that I, J. D. MiNDER, of Killingly, in the county of indham and State of Connecticut, have invented a new and useful Improvement in Machinery for Dressing Sewing-Thread and Cotton and Linen IVarps and other Yarns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying' draw ings, forming part of this specification, in which- Figure l, is a longitudinal vertical section of the machinery, and Fig. 2, is a transverse vertical section of the same.

Similar letters of reference indicate corresponding parts in both figures.

This invention consists in a certain mode of operating a series of brushesto whose action the thread or yarn is submitted after being saturated with size, whereby the dressing is effected without the aid of a fire or blower in a better manner than by revolving brushes. y

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is the framing of the machine.

B, B, B, are a series of parallel shafts, either of which may be the driving shaft of the machine, and all of which are geared tof gether so as to rotate in the same direction by means of spur gears C, C, C, secured upon them near each end, and intermediate gears D, D, D, which are fitted to studs E, E, E, that are arranged on opposite sides of the machine in pairs in line with each other, and which gear with C, C, C.

F, F, F, are a series of spur gears fitted to turn freely on studs Cr, Gr, Cr, that are secured to each side of the framing; said studs being arranged opposite to and in line with each other in pairs, and severally direct-ly under the studs E, E, E. The gears F, F, F, derive motion all in the same direction from gears I, I, I, that are fast to the gears D, D, D.

H, H, H, and H1, H1, H1, are the brushes in two sets, of straight form, provided with journals a, a, a, at their ends, rwhich journals are received within holes made eccentrically in the innerv or facing sides of the gears I, I, I, and F, F, F. The brushes thus arranged in pairs are caused to receive movements similar to those of cranks, and the gears F and I, of each pair are so a1'- ranged that as they rotate, the two brushes of each pair H, H1, vill approach and recede from each other; meeting each other and engaging intimately together in every revolution. The brushes do not rotate on their own axes, but only around the axes of the studs, being prevented turning on their own axes and kept at all times nearly in an upright condition by springs b, and L1, 251, 711, connecting their backs with transverse rails e, c, 0,'and G1, el, 01, that are fast to the framing of the machine.

The thread or yarn (which is represented in Fig. l, in red color) coming from the sizing boX, passes between the two series of brushes H, H, H, and H1, H1, H1, and is held steady by passing over and under sta tionary rods d, el, CZ, arranged transversely to it. The brushes, by the crank movement they receive from the wheels F, F, F, and I, I, I, are made to approach and recede from each other; each pair meeting upon the threads or yarns, which pass midway between them, and moving together very rapidly along t-he thread or yarn away from the sizing box, coming in contact with it at dif ferent points, and brushing oft the superfluous size and laying the fibers even, and smoothing and drying it perfectly.

The above motion of the brushes is proved to be far superior in its effect to the rotary motion employed in the patented process of J. M. Heck; not only giving a better finish to each and every thread, but allowing a much greater number of 'threads to be operated upon at one time.

I do not claim the employment of revolving brushes for dressing sewing thread or yarn. But

What I claim as my invention, and desire to secure by LettersPatent, is:

The employment, for dressing sewing thread and yarns, of a series of straight brushes, arranged in pairs and having a crank mot-ion toward and from each other, so that the several pairs engage and move together along the thread or yarn substantially as described.
